The papermaking industry relies on a delicate balance of chemical processes to produce high-quality paper efficiently and sustainably. At NINGBO INNO PHARMCHEM CO.,LTD., we provide Polyacrylamide (PAM) as a key additive that significantly enhances various stages of the papermaking process. PAM's unique properties as a high molecular weight polymer make it exceptionally effective as a retention aid, drainage aid, and strength enhancer, contributing to improved paper quality and streamlined manufacturing.

In papermaking, fine fibers and fillers are suspended in water to form a slurry. For efficient paper formation, it's crucial to retain these components on the wire mesh while allowing water to drain effectively. PAM acts as an excellent retention aid by flocculating these fine particles. Through mechanisms like bridging and charge neutralization, PAM helps these particles aggregate, preventing them from passing through the mesh with the water. This not only reduces material loss but also improves the overall composition and quality of the final paper product. The specific type of PAM used, such as nonionic or anionic variants, can be selected based on the pH and chemical environment of the paper machine.

As a drainage aid, PAM further accelerates the removal of water from the slurry. The flocs formed by PAM are typically larger and more porous, allowing water to pass through them more readily. This leads to faster dewatering on the paper machine, which can increase production speeds and reduce energy consumption associated with drying. Efficient water management is a critical aspect of paper manufacturing, and PAM plays a pivotal role in this.

Furthermore, PAM contributes to the dry and wet strength of the paper. By binding the cellulose fibers together more effectively, it increases the internal strength of the paper. This can lead to the production of stronger paper products, potentially allowing for reduced basis weights or the use of shorter fiber grades, both of which can result in cost savings and reduced environmental impact. Exploring nonionic polyacrylamide applications in papermaking can offer particular advantages in certain wet-end chemistries.

The versatility of PAM extends to other areas within papermaking, such as improving the efficiency of white water treatment and aiding in the deinking process for recycled paper. At NINGBO INNO PHARMCHEM CO.,LTD., we offer a range of high-quality PAM products suitable for these demanding applications. Our commitment to providing effective solutions, like our industrial grade polyacrylamide flocculant, ensures that paper manufacturers can achieve superior product quality, operational efficiency, and better environmental performance.
